Ram Charan is the only Tollywood star to be present at the pre-wedding festivities of Anant Ambani. In a video clip, we see Mukesh Ambani thanking him and Upasana Kamineni for gracing the occasion on invite.
The Mega Power Star getting an invite to the festivities doesn't bestow upon him a spectacular superstar status. He doesn't become bigger than Prabhas or Mahesh Babu just because the latter were not invited but he was. Charan's fans must not boast that their favourite actor is bigger than others.
Invites to awards ceremonies and festivities like the Ambani one are driven by a lot of PR work. Allu Arjun recently attended an international film festival but even that was driven by commercial interests (promotion of 'Pushpa 2'). Those who invited him and the invitee know it very well. Only fans and trolls don't get such things and are happy to remain naive. Of course, any PR campaign is meant to fool the gullible.
From Bollywood, even actors who haven't had a single theatrical hit in recent years were invited by Ambani's family. On the other hand, the likes of Yash and Thalapathy Vijay were not. Nobody in his senses would say that Charan is bigger than Vijay.
